PATENT OFFICE 13 Claims.

This invention relates to improvements in gas burners and moreparticularly, to burners of the vertically fired type employed forboilers or the like.

Some of the objects of the invention are to provide a short flamevertically fired gas burner that may be easily installed or removed fromthe flre box of a furnace; which will have a wide range of capacity andhigh efliciency; and which will also require only a low first cost.

Another object is to furnish a burner having an improved mixing headwhich although of elongated form will evenly or uniformly discharge thegas throughout the length of the head.

A further object is to supply an elongated mixing head to create aconstant velocity of the gas at all discharge points and thus provide aneven distribution of the flame issuing from the burner.

A still further object is to provide improved means for supplyingsecondary air to be mixed with the gas discharged from adjacent burners.

With the foregoing objects outlined and with other objects in view whichwill appear as the descriptionproceeds, the invention consists in thenovel features hereinafter described, illustrated in the accompanyingdrawings, and more particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is a side elevation partly in vertical section of a portion of afurnace provided with plurality of my improved burners.

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 1 andshowinga pair of the burners in transversevertical section.

Fig. 3 is a view similar to Fig. 2 but showing modification. w 1

Fig. 4 is an enlarged bottom plan view of a removable plate which formsa cover for the burner head.

Fig. 5 is a side elevation of the same.

Figs. 6 and 7 are transverse sectional views of the removable platetaken respectively on the lines 6-6 and 1-1 of Fig. 5.

Referring to Figs. 1 and 2 of the drawings, it is to be understood thatmy improved burners are to be arranged in any suitable furnace settingto which a gaseous fuel is supplied by pipes 8 located in the ash pit(not shown) of the furnace.

At an elevation where the grate of the furnace is usually located, Iarrange spaced plates 9 of "metal or any other suitable material andsuch plates form rigid horizontal supports. Each plate forms rings Ithrough which the down tube ll of a burner may be inserted until itslower 55 end I2 is brought to rest on one of the'pipes I,

which pipe may serve as a support for the burner. Q

The lower end of each tube is provided with a collar 13 which surroundsa nozzle 14 through which the fuel is discharged from pipe 8 into thetube ll. Said tube forms a Venturi throat Hi, the restricted portion ofwhich is arranged direct- 1y above the nozzle l4. Slots I6 at oppositesides of the tube II are preferably positioned below the upper end ofthe nozzle l4 and supply primary air to the burner.

Tube ll terminates at its upper end in an enlarged flared head I!forming an elongated substantially V-shaped groove or channel l8 that,communicates with the interior of the tube ll. Such channel is partiallyformed by upwardly diverging walls I! arranged at opposite sides of thehead 11.

A removable plate 20 forming an important feature of the inventioncooperates with the head I! to provide a mixing head. Such plate, asbest shown in Figs. 4 to 7 inclusive, consists of a flat medial portion2| from which projects upwardly diverging wings 22 that are positionedparallel to the wall l9. Each wing is provided with a series of spaceddepending lugs 23 which rest on the walls l9 and space the wings 22 fromthese walls so as to provide each side 'of the burner head with a seriesof outlets or discharge passageways 24 (Fig. 2).

The inner end of each of the lugs is Preferably of V-shape, as shown at25, to divide the fuel mixture discharged from the head into a number ofstreams.

Each plate is provided at its ends with substantially V-shaped dependingflanges 25a to rest on the ends of the head I! and prevent the mixturefrom discharging through the ends of the head.

Each plate has a pair of parallel depending flanges 26 extendingthroughout the length thereof into the channel I8 and each flange isnotched as shown at 21, 26, 29, the notches increasing in width towardthe ends of the plate. Consequently, the mixture flowing from theVenturi I In order. to create a constant velocity of the gas at allpoints and thus provide an evendistribution of the flame coming out ofthe passageways 24, the varying spaces or notches function to effectuniform distribution. The spaces 21 being I smaller than the spaces 28and 29, decrease velocity at the medial portion of the head while theadjacent sides of two burners will come together Y along a central linebetween two of the burners and there the mixture can be ignited by means-of a pilot burner 30. The latter preferably extends through metalplates II which are removably supported by ledges 32 at opposite sidesof the plates 9, and the plates II are preferably provided with slots 33to permit the upward flow of secondary air. Other openings or ports IIfor secondary air are formed by the rings l0.

Instead ofmaking'the plates 3! flat (Fig. 2) they may be of invertedV-shape, as shown at 3iain1'lg.3. I

From the foregoing it will be understood that the substantially V-shapedthroats of the burner heads are to provide a flame at a -centrallocation between two burners, and this flame will combine with thesecondary air passing through this V-shape construction to cause themixture out 'of the sides of the burners to be combined with secondaryair, especially upon the burning of mixed gases in order to increase thecombustion in a short flame, since an even combustion is practicallyimpossible witha strictly upright flame discharging from a Venturi tube.

Many modifications of the invention will be parting therefrom or fromthe scope f the claims, and since the foregoing disclosure has beengiven byway of example for clearness and understanding, no unnlimitations should be understood, and the appended claims should 5be'construed as broadly as-the state of the art permits.
